All we ask for is thorough investigation into the grisly killings so that the circumstances under which they happened become clear. It is encouraging that the Kenyan and Tanzanian police are working together on the matter.

They should complete the investigations as quickly as is possible and practicable, compile the report and make it public. And the matter should not stop there. Those who will be found to have acted against the law, used excessive force or executed Kenyans must face the full force of the law.
